Heat Transfer Characteristics of Gas-Insulated Transmission Lines
IEEE Power Engineering Review, 1986This paper reports on an investigation of the heat transfer characteristics of GILs under constant temperatures and under changing temperatures influenced by solar radiation and wind. It was verified that values calculated by our heat transfer formulas coincided well with measured values both for current-induced temperature rise of the conductor and ...

Underground links by gas insulated transmission lines
APSCOM 2000 - 5th International Conference on Advances in Power System Control, Operation and Management, 2000The concern to reduce the number of increasingly contested power transmission lines has led utilities and manufacturers as ALSTOM to search for new underground solutions. Today, the penetration of power lines into the heart of large cities is seriously hindered by the density of population and urban expansion.

Handbook for Gas Insulated Substations and Transmission Lines
2012 IEEE Power and Energy Society General Meeting, 2012The Handbook for Gas Insulated Substations (GIS) and Transmission Lines (GIL) will be discussed in a panel session at the General Meeting (GM) of PES in San Diego in July 2012. The original idea for a handbook on GIS and GIL came out of the experiences made with the IEEE tutorials on the same subject which were given more than 20 times around U.S ...

Basic information on Gas Insulated Transmission lines (GIL)
2008 IEEE Power and Energy Society General Meeting - Conversion and Delivery of Electrical Energy in the 21st Century, 2008The GIL is a transmission system for the transmission of high power levels over long distances, to solve specific routing or access problems, or as connections in power plants, and substations. Current ratings of 4000 Amps or more per circuit and distances of several kilometers are possible.

Management of gas-insulated transmission lines magnetic fields
11th International Symposium on High-Voltage Engineering (ISH 99), 1999Recent worldwide attention to the harmful effects of magnetic fields emanating from power lines resulted in a growing motivation to develop methods for magnetic field mitigation aiming at reducing the possibilities of such hazards. In densely populated areas, gas-insulated transmission lines or cables offer an attractive alternative to overhead ...

Research on an Accident of 500 kV Gas Insulated Transmission Line
Applied Mechanics and Materials, 2014Gas insulated transmission line (GIL) is increasingly being utilized in the power system because of its advantages, such as large transportation capacity, no insulation ageing, low loss, and low electromagnetic radiation. However, even GIL equipment in operation can go wrong under the influence of various factors.

Magnetic fields around gas-insulated transmission lines crossing
2001 Power Engineering Society Summer Meeting. Conference Proceedings (Cat. No.01CH37262), 2001Gas-insulated transmission lines or cables (GITL), owing to their compact nature, offer an attractive alternative to overhead transmission lines where space is limited, such as in densely urban areas. Consequently, it is important to address the issue of power frequency magnetic fields emanating from GITL because of concerns that exposure to these ...

Gas insulated transmission lines (GIL): ready for the real world
2000 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.00CH37077), 2002Gas-insulated transmission lines (GIL) are a further development of the tubular conductor intended for long distances and are especially suitable for connecting conurbations to centers of power supply. They are also as "invisible" as ordinary power cables as well as having a number of other advantages.
